Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31547026, here are decompositions:

23 + 31547003 = 31547026
29 + 31546997 = 31547026
89 + 31546937 = 31547026
113 + 31546913 = 31547026
179 + 31546847 = 31547026
227 + 31546799 = 31547026
317 + 31546709 = 31547026
389 + 31546637 = 31547026

Showing the first eight; more decompositions exist.
